Jason Wang 228432551b virtio-rng: make device ready before making request ... Current virtio-rng does a entropy request before DRIVER_OK, this violates the spec: virtio spec requires that all drivers set DRIVER_OK before using devices. Further, kernel will ignore the interrupt after commit 8b4ec69d7e ("virtio: harden vring IRQ"). Fixing this by making device ready before the request. Cc: stable@vger.kernel.org Fixes: 8b4ec69d7e ("virtio: harden vring IRQ") Fixes: f7f510ec19 ("virtio: An entropy device, as suggested by hpa.")
